This spreadsheet completes the design of single pad foundations including a central column. The column can include axial, horizontal and moment forces. The spreadsheet includes a simplified version for fast calculation of straightforward pad foundations. Eccentric Footing Design Excel Sheet. Transformer Calculation Examples. Here are some calculations what I made and from what I build transformers. Transformer: 220V – 2x27V 8A. Input voltage 220 Volts. Output voltage two times by 27 Volts 8 Ampers, simetric for amplifire. EI core intersection square is 50 by 48 milimeters. Reference 1 uses an Excel spreadsheet as the centerpiece of simple flyback-transformer design technique. With the spreadsheet, continuous or dis- continuous-mode flyback-transformer design takes less than 10 minutes. Compare this operation with the tedious, time-consuming task of manually number-crunching more than 50 independent parameters.
The CivilWeb Foundation Design Spreadsheet Suite includes all 12 of our foundation design spreadsheets covering all major spread foundation types. Using these spreadsheets the designer can easily complete any type of foundation design in accordance with either BS EN 1997 or BS 8004. Each spreadsheet also includes unique design and analysis tools which allow the designer to optimise the designs in minutes, saving many hours of detailed design work on every foundation design.
Design your isolated high-voltage power supply as well as the transformer. In this video we will take you through the design process of designing an isolated AC/DC or DC/DC power supply. We will highlight the key design constraints for designing the transformer and show you how the WEBENCH tool designs the transformer for you. Design of core Rectangular core: It is used for core type distribution transformer and small power transformer for moderate and low voltages and shell type transformers. In core type transformer the ratio of depth to width of core varies between 1.4 to 2. In shell type transformer width of central limb is 2 to 3 times the depth of core.

Pad Footing Design Spreadsheet
This spreadsheet completes the design of single pad foundations including a central column. The column can include axial, horizontal and moment forces. The spreadsheet includes a simplified version for fast calculation of straightforward pad foundations.
Eccentric Footing Design Excel Sheet
This spreadsheet completes the design of single pad footings subject to eccentric loading. The spreadsheet allows the designer to position the column anywhere on the footing. The spreadsheet also allows the designer to analyse a footing of any polygonal shape including re-entrant corners and asymmetrical footings.
Combined Footing Design Excel Sheet
This spreadsheet completes the design of rectangular combined footings. The designer can analyse combined footings of any size with two columns placed anywhere on the footing. The columns can include axial, horizontal and moment forces.
Strap Footing Design Excel Sheet
This spreadsheet completes the design of strap footings consisting of two pad footings joined by a connecting structural concrete beam. The spreadsheet calculates the required sizes of both the pad foundations and for the connecting concrete beam. The spreadsheet calculates the bending moments and shear forces in the pads and the beam in order to design the required reinforcement.
Mat Foundation Design Spreadsheet
This spreadsheet can be used to complete the design of mat foundations. The designer can analyse a mat foundation of any size including up to 32 columns placed anywhere on the foundation. The columns can be subjected to axial, horizontal and moment forces. The mat foundation can be analysed as either rigid or flexible depending on the size and thickness of the mat and the strength of the subgrade.
Design of Raft Foundation Spreadsheet
This spreadsheet can be used to design raft foundation subjected to a universally distributed loading. This is suitable for houses and small buildings with a raft foundation. The raft can be designed with a universally distributed loading and linear loads at the edges and corners of the raft.
Strip Footing Design Excel Spreadsheet
This spreadsheet completes the design of strip foundations including up to 16 columns placed anywhere along the strip footing. The columns can include axial, horizontal and moment forces making this spreadsheet suitable for warehouses and other buildings with column loads on long foundations.

Wall Footing Design Spreadsheet
This spreadsheet completes the design of long footings subjected to linear loads from walls. The spreadsheet allows the design to analyse a foundation of any length and width. The wall loads are a universal linear load per metre length of wall. This spreadsheet is suitable for house and small building foundations with wall loads.
Octagonal Vertical Vessel Foundation Design Spreadsheet
This spreadsheet can be used to design octagonal foundations such as those used for vertical vessels or pipelines. The spreadsheet can be used to design octagonal foundations of any size subjected to a single column load.
Beam On Elastic Foundation Spreadsheet
This spreadsheet can be used to model a large or long foundations which behave in a flexible rather than a rigid fashion. The spreadsheet models the system as a flexible beam supported by a Winkler foundation.
Soil Bearing Capacity Calculation
This suite of spreadsheets includes 9 different methods of analysing the bearing capacity of soils. The spreadsheet includes 6 different analytical methods including the Terzaghi, Meyerhof and Hansen methods. The suite also includes 3 different methods of estimating the bearing capacity of soils from site investigation results.
Foundation Settlement Calculation Spreadsheet
This suite of spreadsheets includes all the tools required to complete a settlement analysis of any shallow foundation in any soil. The suite includes 6 different methods of settlement analysis including immediate, elastic, consolidation, differential, Schmertmann settlement and settlement from SI info.
CivilWeb Foundation Design Spreadsheet Suite
The CivilWeb Foundation Design Spreadsheet Suite includes all 12 of our powerful foundation design spreadsheets. The CivilWeb Foundation Design Spreadsheet Suite includes all the tools required to design any common type of shallow foundation in accordance with BS EN 1997 or BS 8004.
